CAR-=COUPLING.

SPECIFICATION forming part Of Letters Patent No. 340,735,631266. April 27, 1886,

Application filed September 26, 1885. Serial No. 178,295. (No model.)

To all whom it may concern:

Be it known that I, JOHN L. SETTY, of North Uniontown, in the county of Highland and State of Ohio, have invented a new and Improved Car-Coupling, of which the following is a full, clear, and exact description.

My invention relates to the construction of oar-couplings, its object being to provide an automatic coupling; and to this end the invention consists of a sliding plate which is moved forward so as to come beneath the point of the coupling-pin by the action of the lever employed to-raise said pin; and the invention consists of certain details of construction and combinations ofparts,to be hereinafter described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of my improved carcoupling, the draw-head being shown in vertical section todisclose the construction and arrangement of the interior parts. Fig. 2 is a plan View of the device, the lever-standard, lever, and coupling-pin being shown in section; and Fig. 3, a detail view of a modified form of sliding plate.

The draw-head A, which is secured to the car in the ordinary manner, is formed with the usual style of hole, a, for the coupling-pin B to restin. Upon the top or upper side of the draw-head there is a heavy boss, b, between which and the draw -head proper there is formed a longitudinal groove or channel, 0, extending as far forward as the hole a. A sliding plate, cl, rests within the channel 0 and projects outward beyond the boss 22. Through this plate d there is passed a downwardlyprojecting pin, 0, which rides in a narrow perpendicular slot, f, formed in the draw-head just back of the hole a.

The conpling'pin Bis connected by a chain, with a lever, N, a second chain, 9, reaching upward from the lever to within reach of the train-men. This lever N is formed with an arm, N, and pivotally mounted in a standard, M, which projects upward from the boss I), the position and formation of the parts being such that when the lever Nis raised the lower end, n, of the arm N will strike against the heel of the plate d and force it forward beneath the point of the pin B, as shown in full lines in Fig. 1.

\Vhen the parts are in the position just referred to, they are ready to receive the coupling-link D,which is carried by the draw-head of another car, (not shown in the drawings) the point of the pin B, thus automatically setting the coupling.

The, slotf is covered by atrap, 0, which provents suow, oinders, 820., from interfering with the working of the parts.

In Fig. 3 I illustrate a modified form of sliding plate, wherein the main body of the plate 1 is thicker and heavier, a small lug or point, (1, being arranged to enter the hole a to support the pin B.

Although such a coupling as I have described is entirely automatic in its action, it may be used in connection with the ordinary form of coupling, and consequently cars supplied with my invention may be placed in any train where couplinglinks are used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combinatiomwith the draw-head and its coupling-pin, of a sliding plate, cl, having a downwardly projecting pin, 0, a lever, N, connected to the coupling-pin, and having an arm, N, substantially as described.

2. The combination,with the draw-head and its coupling-pin, of a sliding plate, d, having a point, d, and being provided with a downwardly-proj ecting pin, (1, alever, N, connected to the coupling -pin, and having an arm, N, said lever being mounted on a standard, M, substantially as described.

JOHN L. SETTY.
